Q. Determine the value of

y

, if

x

is

81

.

\newline

y=\sqrt{x}-11

\newline

Answer:

y=

Write Equation: First, let's write down the equation given for $y$ in terms of $x$ : $y = \sqrt{x} - 11$ Now, we will substitute $x$ with $81$ and calculate the value of $y$ .
Substitute and Calculate: Substitute $x$ with $81$ in the equation: $\newline$ $y = \sqrt{81} - 11$ $\newline$ Now, calculate the square root of $81$ .
Calculate Square Root: The square root of $81$ is $9$ , since $9 \times 9 = 81$ . $\newline$ So, $y = 9 - 11$ $\newline$ Now, perform the subtraction to find the value of $y$ .
Perform Subtraction: Subtract $11$ from $9$ to get the value of $y$ : $\newline$ $y = 9 - 11$ $\newline$ $y = -2$ $\newline$ This is the final value of $y$ .
